[Kenji_lim]

i been in 10 years working in car accessories in Malaysia..tuned so much type of woofer..but i cant get the right tuned for mm 2124 series custom enclosed subwoofer.....any suggestion???

[Thom]

What have you tried? Are you using ported or sealed boxes?

[black magic]

What amp are you using?

[Kenji_lim]

hi..Thom..i am using sealed box..in my sedan car..i cant feel the bass clear in front of driving position..what i know is the bass should be clear and sound should coming to my driving side..i using rockford punch monoblock amp..any suggestion??

[Kenji_lim]

rockford punch monoblock amp..any suggestion???

[Thom]

What size is the box? Have you had another sub in the car that you were happy with before the Momo?

[black magic]

Is it a dvc sub? I can only assume you're using the P3001. If its an svc, 150 watts isn't enough to push that sub. I used to have the same one and I just gave it to my brother. Right now its handling 550 watts.

Where do you have it mounted?

You could be getting some cancellation if its in the front of the trunk and firing into the cabin.

[Kenji_lim]

Hi..Macleod..i place in rear trunk..my amp is powerful enough to handle the woofer..coz i choose so many amp before..maybe the db is too low..or the frequency is not right..any idea???

[MacLeod]

Have you tried facing it in another direction?

[Kenji_lim]

i tried facing in front and rear..same result..maybe this type car seal so tight with so many carpet..in bonnet??BMW 7 series...

[Kenji_lim]

i tried in other car before..the result is good..so nice..;>

[MacLeod]

Oh, that explains it. BWM's are built like tanks and Im not sure but I think there is a pretty solid steel plate seperating the trunk from the cabin and is essentially airtight. If thats the case, thats your problem.

[Kenji_lim]

didt have any solution with this problem???:(
oh my god...what should i do??
changed car??

[Thom]

Are there speakers in the rear deck that could be removed? Like maybe some 7" "subs" that aren't necessary any more?

[Kenji_lim]

got..that mean i need remove it..and let the sound come out? it work?

[MacLeod]

Great idea Thom!

If you have some things you could remove that would let air flow into the cabin from the trunk - that could definitely work. Thats possibly the problem right now, that bulletprood trunk is likely keeping all the bass in the trunk. Opening up some holes would let it into the cabin.

[Kenji_lim]

thank..for helping...much more better now..i can feel the killer bass!!^^

[black magic]

wow. i'm surprised their trunks are actually built that tough.

[Kenji_lim]

:D :D :D :D BMW not suitable for sound sistem???:D :D :D :D :D

[Kenji_lim]

hm...what type of car that can really perform 100% of it sound sistem..maybe we really need to changed bass position...from rear bonet to door side with lot of fiber work and seal like a box...:D :D :p
